Silane coupling agent

Chemical name:3-methacryloxypropyltrimethoxysilane CAS NO. : 2530-85-0 Molecular Formula: CH2=C(CH3)COO(CH2)3Si(OCH3)3 Foreign Company’s Trademark: A-174(America Union Carbon) Z-6030(Dowcorning) KBM-503(ShinEtsu) GF31(Wacker)

PRODUCT PROPERTIES: It is methylpropenylacyloxy silane, Boiling Point:255°C,Flash point:88°C. FEATURES AND BENEFITS: The methacryloxylsilane produced by silane RJ-570. 1.Significantly improves composite strengths when the composite is reinforced with fibreglass roving sized with a typical polyester-compatible formulation.

These formulations normally incorporate silane coupling agents, film-forming resins, lubricants and antistatic agents. 2.Enhances the strength performance, both initially and after wet-conditioning, of cured polyester resin composites filled with silica, glass, silicates and many metal oxides.

3.Enhances the wet electrical properties of many mineral-filled composites, such as crosslinked polyethylene and polyvinyl chloride. 4.May be copolymerized with vinyl acetate and acrylate or methacrylate monomers to prepare silylated polymers that are moisture-curable.

These silylated polymer may be used in coatings, adhesives and sealants to provide superior adhesion and durability.
